Nokia Bluetooth Stereo Headset BH-903

I am using a bluetooth headset for the first time, the new Nokia BH-903 (courtesy of their bloggers program). Instead of hanging on your ear like a Star Trek device, it hangs on your chest with more or less standard earplugs, more like an iPod than a phone device, although with a strong cord behind your neck to hold it up.
I have been wearing it on walks, listening to NPR on its built-in radio receiver. The mouthpiece is embedded on one ear’s wire, and a simple button push leads to answering an incoming call. I inadvertantly speed dialed someone yesterday, by clicking the button without realizing it, so I will have to read that part of the manual closely.
This gizmo only works with more modern Nokia phones, like the N82 that I have been using the past few weeks (great flash!). I am tempted to put at least a few tracks of music on the phone, so I could also listen to music while tromping around. (Hmmm. I might have to get a bluetooth transmitted for my iPod…).
